DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a slim pocket watch with an electronic calculation function.

In recent years, electronic table clocks, wristwatches, and the like have been developed and put into practical use, and recently electronic thin pocket watches have also been considered. This thin pocket watch is roughly shaped like a notebook, and when the lid is closed, only the time is displayed; by opening the lid and operating a switch inside, other information related to the time can be displayed. For example, a calendar is displayed. In this way, with conventional thin pocket watches,
When switching to a display other than the time, it is necessary to open the lid and operate a switch, which is cumbersome.

The present invention has been made in view of the above points, and an object of the present invention is to provide a thin pocket watch with a calculation function that is easy to operate and allows switching from time display to other display simply by opening the lid.

An embodiment of the present invention will be described below with reference to the drawings. 1 and 2 are perspective views of a thin pocket watch of the present invention, in which a lid 2 is attached to a thin watch main body 1 via hinges 3a and 3b so as to be openable and closable. Inside the watch body 1, there are provided a timekeeping circuit, an arithmetic circuit, etc., the details of which will be described later. Also,
On the top surface of the watch body 1, there is provided a display section 4 for displaying time information output from the time measurement circuit or calculation information from the calculation circuit, and keys 5 for giving commands to the time measurement circuit, calculation circuit, etc. is provided. A display section 4 is provided on the lid body 2.
A window 6 is provided in a portion facing the lid body 2.
The display section 4 can be viewed from the outside in a closed state. Furthermore, the watch body 1 includes:
As shown in FIGS. 3a and 3b, a switch 7 is provided close to the side where the hinges 3a and 3b are attached. This switch 7 has an operating section 7a that is connected to the watch body 1.
The spring 7 is provided so as to protrude above the spring 7.
An upward biasing force is always applied by b, so that when the lid 2 is closed, the lid 2 presses the operating portion 7a and closes the switch 7.

Next, the structure of the electronic circuit provided in the watch body 1 will be explained with reference to FIG. 4. In FIG. 4, reference numeral 11 denotes a pulse generator that generates a reference pulse signal of 2 ⁿ Hz, and the reference pulse signal outputted from this pulse generator 11 is inputted to a second/minute/hour counter 12. This seconds, minutes, and hours counter 12 counts the input reference pulse signal and calculates "seconds,""minutes," and "hours."
This unit obtains time information, and a 24-hour cycle signal output from the seconds, minutes, and hours counter 12 is sent to the day, month, and year counter 13. Second minute hour counter 1 above
2 and date/month/year counter 13 are set and modified using the clock function control key 14.
The time information outputted from the second/minute/hour counter 12 is applied to the AND circuit 15 which is the first display control means, and the "day", "month" and "year" are outputted from the day/month/year counter 13. The information is AND circuit 1
Added to 6. Further, the AND circuit 15 is supplied with a +V, that is, a "1" signal via the switch 7. Further, the "1" signal obtained via this switch 7 is applied to a timer 18 and an AND circuit 19 via an inverter 17. When the timer 18 receives a "1" signal, it outputs a "1" signal as a timekeeping operation signal for a certain period of time, and the output signal is applied to an AND circuit 16, which is a second display control means, and an inverter 20.
is applied to the AND circuit 15 via. and,
The output of the AND circuits 15 and 16 is an OR circuit 21
is sent to the display device 22 for display. Thus, the output of the pulse generator 11 is sent to the calculation control section 23 as a timing reference signal.
This arithmetic control unit 23 operates from the output line 25 from the first operation of the arithmetic key 24 such as a numeric keypad or function key to the end of the arithmetic operation, that is, until the lid is closed.
Outputs an operation signal that becomes "1" from a. Further, calculation data is output from the output line 25b of the calculation control section 23. The calculation in progress signal outputted from the output line 25a of the calculation control section 23 is applied to the AND circuit 19 and the inverter 26 that constitute the third display control means, and the inverted output of the inverter 26 is applied to the AND circuits 15 and 16. . The output of the AND circuit 19 is sent to the display device 22 via the OR circuit 21.

Next, the operation of the present invention configured as described above will be explained. A reference pulse signal outputted from the pulse generator 11 is constantly inputted to a seconds/minutes/hours counter 12 for timekeeping operation. The signals output from the seconds, minutes, and hours counter 12 every 24 hours are sent to the day, month, and year counter 13, and this counter 13 performs counting operations for "day,""month," and "year." Data setting and content modification for the seconds, minutes, and hours counter 12 and date, month, and year counter 13 are performed using the clock function control key 14.
When the lid 2 is closed as shown in FIG. 1, the switch 7 is closed and a "1" signal is applied to the AND circuit 15 via the switch 7. In addition, in this state, the output of the timer 18 is "0" and the calculation in progress signal output from the output line 25a of the calculation control section 23 is "0", so the outputs of the inverters 20 and 26 are "1". ”
As a result, the gate of the AND circuit 15 is opened. Therefore, the time information output from the seconds, minutes, and hours counter 12 is sent to the display device 22 via the AND circuit 15, and the time is displayed in hours, minutes, and seconds as shown in FIG. 5a. .

However, when the lid 2 is opened as shown in FIG. 2 while the time is being displayed as described above,
The switch 7 is opened, the signal applied to the AND circuit 15 via the switch 7 becomes "0", and the gate of the AND circuit 15 is closed. Therefore, the time information sent from the seconds, minutes, and hours counter 12 to the display device 22 is blocked by the AND circuit 15, and the display of time is temporarily interrupted. On the other hand, when the signal output from the switch 7 becomes "0", the output of the inverter 17 becomes "1" and is input to the timer 18. When the timer 18 receives the "1" signal, it outputs the "1" signal for a certain period of time (for example, 5 to 10 seconds) and supplies it to the AND circuit 16. At this time, the output of the inverter 26 is "1", so while the output of the timer 18 is held in the "1" state, the AND circuit 16
The gate is opened, and the contents of the date, month, and year counter 13 are sent to the display device 22 via the AND circuit 16 and the OR circuit 21, and the "year" is displayed as shown in FIG. 5b.
The date is displayed as "month" and "day". While this date is displayed, the output of the inverter 20 becomes "0", and even if the switch 7 is closed, the output of the AND circuit 15 is prohibited.

Further, when the lid body 2 is opened and the keys 5, that is, the calculation keys 24 are operated, a calculation in progress signal "1" is output from the output line 25a of the calculation section 23 and is applied to the AND circuit 19. The signal under operation is further inverted to "0" via an inverter 26 and applied to AND circuits 15 and 16. Therefore, the gates of the AND circuits 15 and 16 are closed, and display of time information by the seconds, minutes, and hours counter 12 and date information by the date, month, and year counter 13 is prohibited. Also,
When the lid 2 is opened, the switch 7 is opened, so that the output of the inverter 17 becomes "1" and is applied to the AND circuit 19 as described above. Therefore, when the AND circuit 19 is given a calculation in progress signal from the calculation control unit 23, the gate of the AND circuit 19 opens, and the numeric data, calculation data, etc. output from the output line 25b of the calculation control unit 23 are transferred to the AND circuit 19. 19 and the OR circuit 21 to the display device 22 for display. After the arithmetic processing is completed, when the lid 2 is closed, the initial state is returned and the time information output from the seconds, minutes, and hours counter 12 is displayed in the display position 22.

Next, another embodiment of the present invention will be described with reference to FIG. This embodiment has a calendar display function in addition to a time display function, and the same parts as in the embodiment of FIG. 4 are given the same reference numerals and detailed explanations will be omitted.
